Privacy
This site does not set cookies, does not offer accounts, and stores no personal data. There is no visitor database and no analytics at launch. The only exception is the contact form. A submission is delivered by email through Resend, and only a reply ever uses those details.
The contact form asks for a name, which is optional, an email address, and a message. Submitting it sends two emails: one to the operator and an automatic confirmation to the address you enter. Resend, which delivers email, handles the submission for that delivery only. Vercel hosts this site, and visitor IP addresses can appear in Vercel's server logs for security and operational reasons as part of Vercel's own practice, not a separate collection by this site. If advertising is added later, this policy will change and the page will be updated before that happens. This policy is dated August 2026.
The calculators show both imperial and metric units, and the unit system you choose does not affect how your data is handled.
Does this site use cookies or track me?
No. The site sets no cookies and runs no analytics at launch. There are no accounts and no databases of visitors.
What happens to the details I send through the contact form?
The operator gets your submission by email, and an automatic confirmation goes to the address you give. Resend processes the delivery, and the details are used only to reply. They are not stored in any site database.
Will this policy change if advertising is added?
Adding advertising later will change the policy on this page. The page will be updated before that happens.
